I also think the 35’ was an aircraft limitation.
Seem to recall it was a gotcha in the sim. You would be somewhere to do a cat3 auto land, 3 degree ils all legal on the plate wx wise etc. Land happy ready for medals in the debrief and then shown the TCH and pointed to the limitations in the manual.
If on a normal Ils, manual landing all was fine
But hey that’s from my memory!
